SAFETY RAZOR.

Application filed January 8, 1921.

county of New York, State of New York,

have invented certain new and useful Improvenients in Safety Razors, lof which the following is a specification.

My invention, as herein embodied, is s e-k cially designed for application to the illettetype of safety razor but may, by slight modification, be as readily applied to any other of the well known forms of safety razor now in common use.

The object of the invention is to provide a connection between the razor blade holder and the handle, of a form such as to permit the handle to be folded downward, inl close parallel relation upon the blade-holder, for the purpose of reducing the overall dimensions of the razor, so that it may be carried in a case of practically vest pocket size.

A construction suitable for carrying my invention into effect is illustrated in the accompanying drawing, throughout the several views of which like reference characters indicate like parts.

In the drawings-- Fig. 1, is a central vertical transverse section showing the razor ready 'for use;

Fig. 2, is a central vertical longitudinal section of the same,

Fig. 3, is a view similar to Fig. 2, showing the handle folded down and relatively adjusted to enable the blade holder to be placed in its containing case of approximately vest Vpocket size, and

Figs. 4 and 5, are views similar to Fig. 3,

illustrating modifications. Referring now the drawings: The razor blade holder, here shown of the well known Gillette form, consists of two plates 1 and 2, between which the blade 3 is designed to be clamped, the blade being held therein, in denite relation, by means of guide pins 4, 4, of the lower plate 2, which pass through spaced openings 5, 5, in the blade and enter registering sockets or openings 6, 6, in the upper plate.

Projecting from the lower plate through registering openings of both the blade and the upper plate, there is a stud 7, which is threaded for engagement with a similarly threaded socket 8, formed in the end of the handle 9, the arrangement being such that by screwing the handle down upon the stud,

the plates 1 and 2, are drawn together, se

curely and firmly clamping the blade in position between them ready for' use.

With such a razor there is ordinarily provided a box or case, containing a numbery of spare blades and having a recess or compartment formed therein to receive the bladeholder with the handle attached as above de-- scribed. This necessitates the use of a boxl or case of considerable size; much too large to be conveniently carried in the pocket and is objectionable for that reason.

In order to overcome this objection and at the same time avoid the manyk obvious disadvantages of employing a separable or detachable handle to accomplish it, I provide a connection, which I will now describe, between the upper blade-holding plate and the handle, which enables the latter to be swung downward, into parallel relation with the plate and shifted lengthwise thereof, so as to project equally beyond the ends.

Trunnioned on the reduced ends of screws 10, 10, projecting from posts 11, 11, fixedA to the upper clamp-plate, there is a guide ring 12, proportioned to loosely encircle that portion of the handle included between annular stop shoulders 13 and 14. l

As arranged, the trunnioned bearings permit the handle to be swung either to the right or left. When standing upright or at right angles to the plate, the threaded socket 8, in the end of the handle, is held by the guide ring 12, in centered relation to the projecting threaded stud 7, of the lower clamp plate, in position to engage the same upon being rotated and draw the plates together to clamp the razor blade between them, as above described.

To adjust the handle from the position shown in Fig. 2, to that shown in Fig. 3, it is first rotated toward the left or counter clockwise, to disengage it from the threaded stud 7 and permit the lower clamp plate to be removed temporarily.

After the handle is swung downward on the upper plate and shifted through the guide ring 12, until checked by the annular stop shoulder 14, locatedat about the midpoint of the handle, the lower plate is replaced; arecess or socket 15 being provided in the guide ring and handle to accomodate ghe projecting end of the stud 7, as shown in With the handle adjusted as just olescribed, the over-all dimensions of the razor are reduced to such an extent as to enable it to be placed in a case of practically the same size as that ordinarily used for eye-glasses and conveniently carried in a coat 0r vest pocket, as will be apparent.

lf desired, the opening or socket 15 in the guide ring, may be threaded to engage the stud 7 as shown in Fig. 4, in which case the clamp plates could not be brought into such close relation as in Fig. 3, but would be posi tively secured together.

A 'somewhat similar effect is also obtain` able by the construction shown in F ig. 5, in which the handle is detachable; the above de scribed connection between the handle and the upper clamp plate is dispensed with and the transverse opening l5a threaded for en` gagement with the stud 7.

Having, therefore, described my inveir tion, I claim-d 1. An adjustable handle connection for a safety razor blade holder comprising a trunnioned guide on the holder loosely encircling the handle, which latter is free to rotate and slide therein.

2. An adjustable handle connection for a safety razor blade holder comprising an anw nular guide trunnioned on the holder loosely encircling the handle and stops 0n the handle limiting its movement in the guide.

3. A safety razor comprising two plates between which the razor blade is adapted to be clamped, one of the plates being provided with a threaded stud and the other plate with an opening to receive the stud, a handle tap` ped and threaded at one end to engage the stud and a ring guide trunnioned on one of the plates and loosely encircling the handle to permit rotary and rectilinear motion thereof.

4:. A safety razor comprisingtwo plates between which the razor blade is adapted to be clamped, one of the plates being provided with a threaded stud and the other plate with an opening to receive the stud, a handle having openings therein spaced apart to re` ceive the stud in different positions of adjustment of the handle, and a ring guide trunnioned on one of the plates and loosely encircling the handle to permit rotary and rectilinear motion thereof.

A5. A safety razor comprising two plates between which the razor blade is adapted toy be clamped, one of the plates being provided with a threaded stud and the other plate with an opening to receive the stud, a handle having openings therein threaded and suit-v ably spaced apart for engagement of the threaded stud in different positions of adjustment of the handle, and a ring guide trunnioned on one of the plates and loosely encircling the handle to permit rotary and rectilinear motion thereof. f
